Having some troubles selecting distinct rows.
[Code]....
This is not giving me the wanted results.
Two models:
[code]....
Each ContentVersion is linked to Content through the ContentID.
I want to select all "Content" where UserID = X, then for each selected "Content" I want the latest "ContentVersion".
The return type should be of type <IQueryable>ContentVersion.
I would like to select a distinct query based on three fields and display the rest of the fields. For example,
I have firstname, lastname, address, city, state and zip, but I only want to use the distinct on these fields first and last name. However when i use the distinct function I get a distinct on all the selected rows. I just want to distinct firstname and lastname and display the other fields. for example,
Mary Smith New York
Mary Smithy New York
Mary Smith Maine
I would like the result to be:
Mary Smith New York
Mary Smithy New York
I don't care about Mary Smith Maine, because i am only using the distinct for "Mary Smith" firstname and last name and showing the city.

This is something I can easily do in SQL, but I'm pretty new to LINQ and haven't been able to find an answer online.
I need a LINQ query that returns two values; the first a distinct value and the second the count of the first value. This is filtered by a parameter. Here is my table:

I have an already created DataTable object which i am using for my girdview (asp.net) i also need to bind a column of that object to a DropDownList. The datatable has the correct details in the column but the column contains more that 1 of the same name in the column - hence I would love to just do some kind of SELECT DISTINCT on the datatable and copy it to a new datatable for use with binding the dropdown.
This would allow me to save resources by making another trip to the database.
Here is an example, the current datatable has a column called items and in this column has the following entries
1
1
1
1
5
5
6
And of course i need only unique items for binding to my dropdown, hence i need the following data
1
5
6
Of course i don't want to change the original datatable object but rather make a copy of it will the new details.

I'm using asp.net login on a SQL Database.
I have 12 users in my User tabel - one of the user I don't want to have in my select (the user is an admin).
I tried this:
[Code]....
I also tried:
WHERE (dbo.aspnet_Roles.RoleName <> 'Administrators')
Both time it took the user into the table....
If I instead try this
WHERE (dbo.aspnet_Roles.RoleName = 'Administrators')
I get only one row (as expected).
What is wrong with the above sql statement - why can't I get 11 users and not them all (12 users)?

I am using C# + VSTS 2008 + .Net + ASP.Net + IIS 7.0 + ADO.Net + SQL Server 2008. I have a ADO.Net datatable object, and I want to filter out duplicate/similar records (in my specific rule to judge whether records are duplicate/similar -- if record/row has the same value for a string column, I will treat them as duplicate/similar records), and only keep one of such duplicate/similar records.
The output needs to be a datatable, may output the same datatable object if filter operation could be operated on the same datatable object.
What is the most efficient solution?
